There is a good bit of information out there on the Web about Larabanga, mostly due the beautiful sudanese-style mosque--Ghana's oldest--in the village. In addition, it sits more or less at the entrance to Mole National Park so anyone (with any minimum of curiousity) who visits the park will get to Larabanga.
At the moment, and given the dynamic nature of the information out there, the best thing to do is just google "Larabanga".
